GATE

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed. July 6, 1908. Serial No. 442,182.

To all whom it may concern:

Be it known that 1, JOHN J. PLOWMAN, a citizen of the United States,residing at Waterport, in the county of Orleans and State of New York,have invented certain improvements in gates and especially in a novelconstruction of vertical folding gate, means being provided for holdingthe latter in different adjusted positions.

The invention comprises various details of construction, combinationsand arrangements of parts which Will be hereinafter fully described andthen specifically defined inthe appended claims.

l illustrate my invention in the accompanying drawings, in which Figure1 is a side elevation of my improved gate, showing the same held in aralsed posit1on. Flg. 2 1s a central vertical sectional view throughparts of the invention, showing the gate at its lowest position and heldclosed, and Fig. 3 is a detailed view of the gate latch.

Reference now being had to the details of the drawings by letter, Adesignates the rear gate post and B the front post or one adj acent tothe free end of the gate. Said post B is provided with an opening B atany suitable location adapted to receive a gate latch C. The ate is madeup of the longitudinal strips l) which are pivotally connected to thecross-pieces E and so arranged that the longitudinal strips may swinginto different inclined positions, as shown in Fig.

-7 1 of the drawings.

F designates a gripping clamp, made preferably of metal, and passesabout the end cross-pieces E adjacent to the post A, and the ends ofsaid gripping clamp F project laterally beyond the edge of the post Aand carry a pivot pin G u on which the cam lever I is mounted, whichever is adapted to bear frictionally against the outer face of the postA to hold the gate in different vertical posil longitudinal bars of thegate and havin 110 7 tions.

Guide wings K are fastened to the end of the cross-pieces of the gateand serve to guide the gate in its vertical movements. A ratchet bar Nis pivotally connected to the strips D, and O is a weighted pawlpivotally mounted upon a pin upon one of the strips of the gate and thecontracted end of the pawl O is adapted to enga e automatically one oranother of the teeth upon said latch bar for the purpose of holding thegate at an inclination, as shown in Fig. 1 of the drawings. Said latchbar C is provided with notches C and P is a link pivotally mounted upona ivot P and is adapted to engage one or anot er of the notches C forthe purpose of holding the latch in a locking position. A pin Q, shownin Fi 3 of the drawings, extends through the atch and is adapted tocontact with the forward edge of the crosspiece N to limit the movementof the latch away from the free end of the gate. Said latch C rests uponone of the longitudinal strips D, as shown in Fig. 2 of the drawings.

The operation of my gate is as follows When it is desired to raise thegate, the friction cam lever I is swung into such a position that itwill be free from the gate post A, thus allowing the gate to be moved upor down. By pulling the cam lever down, it will frictionally engage andhold the gate in the desired position. If it is desired to tilt the ateup so that the longitudinal strips will be (is osed at inclinations to avertical plane an. still remain parallel with one another, the forwardend. of the gate is raised and the gravity pawl will automaticallyengage a notch and hold the gate suspended. By pushing the latchforward, the pivotal link P will automatically engage a notch and holdthe same in the position shown in Fig. 2 of the drawings.

What I claim to be new is 1. A folding panel gate having longitudinalcross strips pivotally connected together, a post and means for holdingone end of the gate adjustably thereon, a rack bar pivotally connectedto the longitudinal strips of the gate, a strip pivotally connectingsaid rack bar and the cross bar and the free end of the gate, a gravitypawl pivoted upon said strip and having a weighted end adapted tonormally throw the pawl into engagement with the teeth of said rack bar,a link pivotally mounted upon said rack bar, and a sliding catch mountedupon one of the teeth adapted to be engaged by the free en 1 of saidlink, as set forth.

,. adapted to normally throw the pawl into! 2. A folding panel gatehaving longitu- 'bar, a sliding catch mounted to have a dinal crossstrips pivotally connected to- 1 longitudinal movement upon one of thegether, a post and means for holding one endlongitudisn-al bars of thegate, a pin project 15 of the gate adjustably thereon, a rack bar l ingfrom the opposite faces of said catch, a pivotally connected to thelongitudinal i pivotal link mounted upon the rack bar and. strips of thegate, a strip pivotally connectadapted to engage said catch, as setforth. ing said rack bar and the cross bar and the In testimony whereofI hereunto affix my free end of the gate, a gravity pawl pivoted:signatrue in the presence'oi two Witnesses. 20 upon said strip andhaving a Weighted end JOHN J.
